Vintage mint green oversized collar jacket, M/L

Vintage mint green oversized collar jacket. No brand or size listed, fits like size M/L. I usually wear size M and this fits loose on me. Length approx. 41”, bust 21.5”, sleeves from armpit to cuffs approx. 14.5”, shoulder approx. 17.5”. Material feels like cotton blend. In great condition with no noticeable flaws. Fully lined, two big pockets on the front, oversized collars. The lining is a bit longer than the jacket, ( please check pictures)—this may be a handmade piece. No lowballing please.
